Samenvatting
The ac/ac Modular Multilevel Converter (MMC) has emerged as a popular front-end converter solution in Medium-Voltage (MV)-connected applications, such as chargers, solid state transformers, and medium voltage drives. Typically, carrier-based pulse width modulation is employed to generate the insertion index and, consequently, the arm voltages of the MMC. This paper studies the impact of phase adjustment of carrier waveforms on the Total Harmonic Distortion (THD) of the input and output terminal quantities. A trade-off is found between the THD of the MMC's input and output voltage waveforms, providing insights into optimizing voltage and current waveform quality for practical applications. Simulations and experimental measurements validate the presented theoretical analysis.
